AN IMPROVED TECHNOLOGY FOR TREATMENT OF COAL TO MINIMISE IMPREGNATED IMPURITIES BY ULTRA SOUND ENERGY ADAPTABLE IN MINERAL BENEFICIATION

摘要

The present invention relates to an improved method for treatment of coal to minimize impregnated impurities in coal by ultrasound energy adaptable in mineral beneficiation comprises a coal slurry containing coal and water mixture in the weight ratio 1:10 and an ultrasound transducer excites the coal slurry in a frequency of 22 kHz to cause reduction of its impurities like ash, sulpher, phosphorus, gangue material from coal and a physically separating device as cyclone separators or vibrating screens or centrifuge separator or spiral separator to separate and recover coal with reduces ash, sulpher coal with reduced ash, sulpher, phosphorus, volatile matter, gangue content.
